Detection and Estimation of Ochratoxin A [PDF]
THE recent isolation1 of ochratoxin A from Aspergillus ochraceus Wilh., which has a widespread natural distribution, made the development of a rapid method for the detection and estimation of the mycotoxin desirable. The following methods have been used during screening of fungal strains and media for toxin production.

Efficacy of Ammonization to Eliminate Common Mycotoxins
Mycotoxin is a worldwide problem threatening animal health and performance as well as public health. The objective of this experiment was to test the effect of ammonization on elimination of common mycotoxins in laying hen compound feed (CF) and dairy ...

The occurrence of ochratoxin A in coffee [PDF]
Ochratoxin A (OA) is a nephrotoxic and nephrocarcinogenic mycotoxin which is predominantly produced by the two ubiquitous fungal genera, Aspergillus and Penicillium. OA is found in foodstuffs, predominantly in cereals but also in coffee beans. Inconsistent results have been published regarding the influence of roasting on the OA content in roasted ...

Metabolism of ochratoxin A by rats [PDF]
Albino rats were given ochratoxin A (6.6 mg/kg body weight) intraperitoneally or per os. Independent of route administration, 6% of a given dose was excreted as the toxin, 1 to 1.5% as (4R)-4-hydroxyochratoxin A, and 25 to 27% as ochratoxin alpha in the urine.

Review of mycotoxin reduction in food and feed: from prevention in the field to detoxification by adsorption or transformation [PDF]
Mycotoxins are secondary metabolites present worldwide in agricultural commodities and produced by filamentous fungi that cause a toxic response (mycotoxicosis) when ingested by animals.
